Host-Specific Parameters in Solaris Secure Shell

If it is useful to have different Solaris Secure Shell characteristics for different
local hosts, the administrator can define separate sets of parameters in the /etc/ssh/ssh_config file to be applied according to host or regular
expression. This task is done by grouping entries in the file by Host keyword.
If the Host keyword is not used, the entries in the client
configuration file apply to whichever local host a user is working on.
